NASA Again Delays Launch of Troubled Webb Telescope (nytimes.com)

In a blow to NASA's prestige and its budget, America's next great space telescope has been postponed again. From a report: NASA announced on Wednesday that the James Webb Space Telescope, once scheduled to be launched into orbit around the sun this fall, will take three more years and another billion dollars to complete. A report delivered to NASA by an independent review board estimated that the cost of the troubled Webb telescope would now be $9.66 billion, and that it would not be ready to launch until March 30, 2021.

    The problem is, a lot of contracts ARE fixed price. However, if you know how it works, it's fixed price as long as whole list of conditions are met - if any of them are violated, the price starts rising.

    This can include stuff like "the work will be done in XX state" and some politician wants it done in their state. So now the company tacks on the costs of moving the workforce over to the price of the bill.

    I've written a few fixed price contracts - you cover as much ass as possible, so when the customer comes up and changes something, you soak them. This includes stuff like requirements as well, plus contingency and other amounts. We always warn them when something else they want causes a change request, as that adds to the cost they will have to pay.

    Fixed price contracts are generally the rule, which is why everyone covers their ass because they know there will be changes, and those changes will add time and cost to the project so they get billed for.

    And yes, you build in things like start/stop costs - if the customer causes a stop work for any reason (e.g., fail to deliver required deliverables on time, the stopping and starting of the project incurs costs that have to be recouped as well. Any time there's a "changing of the guard" all of a sudden can cause all this as the outgoing guy simply walks away and the incoming guy has to step in and pick everything up.

    Cost Plus (or Time and Materials) isn't always more expensive than Fixed Price - careful contract writing ensures that Fixed Price contracts have sufficient bloat to factor in risk, as well as sufficient CYA to ensure if the user wants a change, they will pay for it.

    It's not old, it's not outdated, and the sunk cost fallacy is inappropriate in this case. If the project is scrapped, NASA has a ten billion dollar paperweight sitting in a warehouse because you don't want the government to spend the equivalent of pocket change on a space telescope.

    Another billion dollar (and it's likely going to exceed that) is not pocket change. It's more than the original cost estimate for the entire mission.

    For comparison, the New Horizons program cost around $700 million all in all. Dawn was around $500 million.

    And new technologies not available at the time those missions were planned, and certainly not when JWT was planned, are available now, giving more bang for the buck.

    This is a prime example of sunken cost fallacy, where people feel obliged to continue because of how much has already been put into the program, instead of looking only at how much we need to put in from now on, no matter how much was put into it in the past.

    Our atmosphere is opaque to infrared. So any infrared astronomy has to be done from space. Hubble can only do partial infrared (specifically near-infrared), not the rest of the infrared spectrum.

    Infrared is needed because it can peer through dust clouds. See this image of Eagle Nebula in visible vs. near infrared by Hubble to see the difference.

    JWST works mainly in infrared, near and far. Moreover, it has much more aperture than Hubble (~ 2.4 meters vs 6.5 meters).

    All this means that JWST can see back in time when the first stars that shined in the cosmos, and shed light on how the Big Bang progressed. Important stuff, and no instrument compares to its capabilities.

      Agreed, but I'd like to see an interferometry array. Space telescopes are necessarily small, so we need multiple to get the resolution and sensitivity.

      What? How can you possibly believe that? Have you ever looked at a solar spectrum? Gebus:

      Yes, there's some rather large holes, but there's also some rather larger areas that are even more transparent than visible. The key ~5 micron area is indeed blocked, but that doesn't stop all sorts of IR work here on the ground - you know, like the "NASA Infrared Telescope Facility"

      Yes, you are right, it is not totally opaque. But there are holes, like you said.

      And still, water vapour in our atmosphere absorbs a lot of infrared. Water is a green house gas. So the best observation for IR is above the atmosphere.

      So to get over the holes and water vapour, we have things like like SOFIA, which is not 6 meters, and then you have JWST with the sun shield.

    SpaceX uses technology which has already been developed elsewhere. Therefore, they know what to expect. The Webb is new. Many parts of it have never existed before. Therefore, it is impossible to use other projects as a baseline for cost estimation.

    The U.S. government wastes that on bridges to nowhere, Trump's golfing excursions and funding strip club excursions by the U.S. military.

    So, yes, if they don't give a shit about those, then set billion is chump change.

    Besides which, it's about the ROI . The military either offers no ROI, or a negative value depending on whether cleaning up the mess afterwards counts. The telescope has positive ROI, so the net cost is below the sticker price.

    The U.S. subsidizes coal and oil to the tune of hundreds of billions a year. If you cut the subsidies, you could have a giant flotilla of Webb telescopes as an interferometer.

    When you're willing to burn money on ego projects, you don't get to excuse not spending money on real stuff.

    You can't do infrared from Earth. There is no Earth-based telescope that can do it, nor will there ever be. You know this, so why create complaints you know are bogus?

    If it's costing too much, it's because people demanded the lowest bid rather than the best bid and then demanded NASA have a smaller budget AND THEN kept changing NASA's directives.

    Give it the money needed to do the job, then get the hell out of the way.
